ion relates to stools and more stool adapted for the use d the like, and has for its objects to provide a stool mounted upon a resilient standard, permitting the dentist or other person occupying the stool tree movement in any d irection, means being provided Jfor limiting the movement ot the resilient standard and for normally holding the saine upright means quickly adjusting the being also provided tor height of the stool and holding theseat thereof in any desired adj ustment.

The above and other'objects may be attained by constructing the stool in the manner illustrated in the accompanying drawings, in which- .Figure 1V is a stool constr va vertical, sectional view of ucted in accordance with the invention, showing the saine in the normal position;

Fig. 2, a se portion of the ctional view of the lower end standard showing the fieXible connection thereof in the vflexed position;

Fig. portion of th 3, an enlarged section of the upper e standard, showing the seat shank in the raised position; and

Fig. 4, a sec Similar nu tion on the line 1-'--4, Fig. 3. merals ot reference indicate corresponding parts throughout the drawings.

The device comprises the base 1 preferably ed beneath and in alignment with the neck to receive the threaded portion of the stein.

-which projects upward through the center of the spring coil 6, the lower end portion of which is threaded into the spiral grooves 3 of the neck,

thereof is threaded into similar grooves the lower end lower extremity of the the shouldered portion 4 while the upper end portion 7 in ot the tubular standard 8, the spiral resting upon of the base and the upper extremity thereof engaging the shoulder 9 of the standard.

A loose sle portion ot the spiral surrounds the central 6 and is provided with eve 10 the annular recess 11 in its lower end to receive the upper end of the tubular the base, an a ed in the 'upp the lower end neck 2 of nnular recess 12 being provider end of the sleeve to receive portion oit the tubular stein 8,

gages the shoulder 9 in the tubular standard and the upper end thereof engages the closed upper end 19 'of the tubular guide 17. The shank 18 is provided along vone side with the vertical groove 20, the sockets 21 being located at intervals in said groove and arranged to be engaged by the spring pressed plunger 22,' slidably mounted in the transverse bore 23 formed in the boss 24 at the upper end of the tubular standard, a shoulder 25 being formed upon said plunger and arranged to engage the inner end of the bore 23 and the bushing 26 to limit the movement ot the plunger in opposite directions.

A coil spring 27 surrounds the plunger 22 within the bushing 26 and is engaged at opposite ends with the shoulder 25 upon thc plunger and with the screw cap 28 upon 4the outer end of the boss 24.

A nut 29 is mounted upon the outer screw threaded end 30 of the plunger and the outer portion of the plunger is provided with the upper and lower longitudinal groovesv 31, which receive the lugs 32 upon the nut 3?), which is carried in the tubular handle 34.

By tilting the handle 34 as shown in Fig. 3, opposite sides of the nut 33 will engage the screw cap 28 and the nut 29, pulling the plunger longitudinally forward as shown in said figure, releasing the plunger from the sockets 21 and permitting the coil spring 16 to raise the shank 18 until the shoulder 35 at the lower end of the groove 20 engages the plunger 22.

The seat of the stool comprises the metallic frame or disk portion 36 provided with the depending socket 37 which receives the upper end of the shank 18, a set screw 38 or the like being located in the socket and eX- tending into the annular groove 39 in the shank to retain the frame thereon. A suitably upholstered seat 40 is fixed upon the frame 36.

In adjusting the seat to the desired height, one hand should be placed upon the seat. 40 and handle 34 should be tilted with the othoi` hand, as shown in Fig. 3, releasing the plungerI 22 from the notches 2l.

If it is desired to raise the seat, the pressure upon the same should be lessened, permitting the coil spring 16 to raise the seat to the desired height, at which time the handle 34 is released, permitting the plunger to engage the nearest socket 2l.

It it is desired to lower the seat, the plunger 22 is released in the same manner and the seat depressed by hand to the desired position, when the plunger 22 is again engaged with the nearest socket 2l, holding the seat in this adjustment.'

lVith the construction shown, the user of the stool may easily move in any direction by leaning his weight in the direction desired, tilting the standard 8 upon the coil 6,V the sleeve l0, as shown in Fig. 2, engaging the adjacent sides of the ltubular neck 2 of the base andthe lower end of the tubular standard 8, while the opposite side of the coil 6, engaging the stem 5, limits the movement ot the standard.

I claim Y l. A device of the character de cribed including a base having a tubular neck portion, a stem extending upward through the neck portion, a coil scated in the neck portion surrounding the stem, a seat standard mounted upon the upper end of the coil, and a loose sleeve resting upon the neck and surrounding the coil and arranged to be engaged by the seat standard when the coil is flexed.

2. A device of th-e character described including a base having a tubular neck portion, a stem extending upward through the neck portion, a coil seated in the neck portion surrounding the stein, a seat standard mounted upon the upper end of the coil, and a loose sleeve resting upon the neck and surrounding the coil and arranged to be engaged by the seat standard when the coil is flexed, said sleeve being internally upwardly flared.

3. A device of the character described including a base having a tubular neck portion, a stem ext-ending upward through the neck portion, a coil seated in the neck portion surrounding the stern, a seat standard mounted upon the upper end ot the coil, and a loose sleeve resting upon the neck and surrounding the coil, the upper and lower ends et the sleeve being annularly recess-ed to receive the adjacent end portions of the neck `and standard.

4. A device of the character described including a base having a tubular neck portion, a coil seated in the neck portion. a seat standard mounted upon the upper end of the coil, and a loose sleeve rest-ing upon the neck and surrounding the coil and arranged to be engaged by the seat standard when the coil is flexed.

5. A device of the character described including a base having a tubular neck portion, a coil seated in theV neck portion, a seat standard mounted upon the upper end ol" the coil, and a loose sleeve resting upon the neck and surrounding the coil and arranged to be engaged by the seat standard when the coil is flexed, said sleeve being internally upwardly flared.

6. A device of the character described including a` base having a tubular neck portion, a coil seated in the neck portieri, a seat .standard mounted upon the upper end ot the coil, and a loose sleeve resting upon the neck and surrounding the coil, the upper and lower ends of the sleeve being annularly recessed to receive the adjacent end portions of the neck and standard.

7. ,A stool including a tubular standard, a shank slidably mounted therein and having a seatl mounted at its upper end, said shank having a longitudinal groove `and spaced notches communicating therewith, a spring pressed plunger extended into the groove and arranged to be normally seated in one ol the sockets, a shoulder at the outer Aend of the plunger', and a hollow handle surrounding the plunger and provided with a portion located between the shoulder upon the plunger and the standard, longitudinal grooves in the plunger and lugs upon the hollow handle engaging said grooves whereby a tilting of the handle will move the plunger out ot' enga-gement with the socket-s.
